Fitness Tip of the Day: Monday's Muscle Work -- Bob Harper's Butt Burn Challenge

In addition to whatever other muscle work or cardio you choose to do today,  I found a video from Bob Harper entitled the "Butt Burn Challenge" that I encourage you to do.

All you need for this challenge is a step or sturdy box 6-12 inches high.  You can also do this standing on the floor; your glutes will still be challenged.

I would do this challenge first, after your warm up while your muscles are fresh.  The challenge is about 3 minutes long (50 reps each side).
